If you were to do an engine swap, what would you put in a YJ?

i have a 350 and a hydro350 trans from a 79 Cheyenne. the left bank has a blown head gasket. trans is solid if i remember right. i sell the combo cheap. i don't know the miles on it. pm me if your interested in a sb.

when you are talking about doing a head swap with a 4.0 head. there are 3 different model heads for the 4.0 which one are you refering too? all are for fuel injection. he doesn't state if he has a injection model or a crab. engine.
